Manual Accuracy

The mill/drill is used to shape metal workpieces

by removing material with the use of a rotating

cutting tool.

In milling operations, the location of the cutting

tool is stationary while the workpiece is fed into

the cutter by moving the table.

In drilling operations, the workpiece is held sta-

tionary on the table while the cutting tool is fed

vertically into the workpiece with the movement of

the spindle and head.

Additional Safety for Mill/Drills

UNDERSTANDING CONTROLS. Make sure you

understand the use and operation of all controls.

SAFETY ACCESSORIES. Always use a chip

guard in addition to your safety glasses when mill-

ing to prevent bodily injury.

WORK HOLDING. Before starting the machine,

be certain the workpiece has been properly

clamped to the table. NEVER hold the workpiece

by hand when using the mill.

CHUCK KEY SAFETY. Always remove your

chuck key, drawbar wrench, and any service tools

immediately after use.

SPINDLE SPEEDS. Select the spindle speed

that is appropriate for the type of work and mate-

rial. Allow the mill/drill to gain full speed before

beginning a cut.

POWER DISRUPTION. In the event of a local

power outage during use of the mill, turn OFF all

switches to avoid possible sudden start up once

power is restored.

SPINDLE DIRECTION CHANGES. Never

reverse spindle direction when milling, boring, or

facing a workpiece.

STOPPING SPINDLE. DO NOT stop the mill/drill

using your hand against the chuck.

BE ATTENTIVE. DO NOT leave mill/drill running

unattended for any reason.

Model G0705 (Mfg. since 09/09)

SECTION 2: POWER SUPPLY

Availability

Before installing the machine, consider the avail-

ability and proximity of the required power supply

circuit. If an existing circuit does not meet the

requirements for this machine, a new circuit must

be installed. To minimize the risk of electrocution,

fire, or equipment damage, installation work and

electrical wiring must be done by an electrican or

qualified service personnel in accordance with all

applicable codes and standards.

Electrocution, fire, or

equipment damage may

occur if machine is not

correctly grounded and

connected to the power

supply.

Full-Load Current Rating

The full-load current rating is the amperage a

machine draws at 100% of the rated output power.

On machines with multiple motors, this is the

amperage drawn by the largest motor or sum of all

motors and electrical devices that might operate

at one time during normal operations.

Full-Load Current Rating at 220V .... 8.6 Amps

Full-Load Current Rating at 110V .... 17.8 Amps

The full-load current is not the maximum amount

of amps that the machine will draw. If the machine

is overloaded, it will draw additional amps beyond

the full-load rating.

If the machine is overloaded for a sufficient length

of time, damage, overheating, or fire may result—

especially if connected to an undersized circuit.

To reduce the risk of these hazards, avoid over-

loading the machine during operation and make

sure it is connected to a power supply circuit that

meets the requirements in the following section.

For your own safety and protection of

property, consult an electrician if you are

unsure about wiring practices or electrical

codes in your area.

Note: The circuit requirements listed in this man-

ual apply to a dedicated circuit—where only one

machine will be running at a time. If this machine

will be connected to a shared circuit where mul-

tiple machines will be running at the same time,

consult a qualified electrician to ensure that the

circuit is properly sized for safe operation.

A power supply circuit includes all electrical

equipment between the breaker box or fuse panel

in the building and the machine. The power sup-

ply circuit used for this machine must be sized to

safely handle the full-load current drawn from the

machine for an extended period of time. (If this

machine is connected to a circuit protected by

fuses, use a time delay fuse marked D.)

Improper connection of the equipment-grounding

wire can result in a risk of electric shock. The

wire with green insulation (with or without yellow

stripes) is the equipment-grounding wire. If repair

or replacement of the power cord or plug is nec-

essary, do not connect the equipment-grounding

wire to a live (current carrying) terminal.

Check with a qualified electrician or service per-

sonnel if you do not understand these grounding

requirements, or if you are in doubt about whether

the tool is properly grounded. If you ever notice

that a cord or plug is damaged or worn, discon-

nect it from power, and immediately replace it with

a new one.

Extension Cords

We do not recommend using an extension cord

with this machine.

If you must use an extension

cord, only use it if absolutely necessary and only

on a temporary basis.

Extension cords cause voltage drop, which may

damage electrical components and shorten motor

life. Voltage drop increases as the extension cord

size gets longer and the gauge size gets smaller

(higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must

contain a ground wire, match the required plug

and receptacle, and meet the following require-

ments:

Minimum Gauge Size ...........................12 AWG

Maximum Length (Shorter is Better).......50 ft.

Grounding Requirements

This machine MUST be grounded. In the event

of certain malfunctions or breakdowns, grounding

reduces the risk of electric shock by providing a

path of least resistance for electric current.

Serious injury could occur if you connect

the machine to power before completing the

setup process. DO NOT connect to power

until instructed later in this manual.

For 220V operation: This machine is equipped

with a power cord that has an equipment-ground-

ing wire and a grounding plug (see following fig-

ure). The plug must only be inserted into a match-

ing receptacle (outlet) that is properly installed

and grounded in accordance with all local codes

and ordinances.

For 110V operation: The plug specified under

“

Circuit Requirements for 110V” on the previ

-

ous page has a grounding prong that must be

attached to the equipment-grounding wire inside

the included power cord. The plug must only be

inserted into a matching receptacle (see below)

that is properly installed and grounded in accor-

dance with all local codes and ordinances.

Voltage Conversion

The voltage conversion MUST be performed by

a qualified electrician. To perform the voltage

conversion, follow 110V Conversion on the next

page. If the diagram included on the motor con-

flicts with the one in this manual, the motor may

have changed since the manual was printed. Use

the diagram provided on the motor.

110V Conversion

The Model G0705 can be converted for 110V

operation. This conversion job consists of dis-

connecting the machine from the power source,

replacing the contactors and power indicator

lamp, and rewiring the motor.

The necessary components for this procedure

can be purchased in the Model G0705 110V

Conversion Kit (Part No. P0705311) by calling

Grizzly Customer Service at (800) 523-4777.

All wiring changes must be inspected by a quali-

fied electrician before the machine is connected

to the power source. If, at any time during this pro-

cedure you need help, call Grizzly Tech Support

at (570) 546-9663.

To rewire the Model G0705 for 110V opera-

tion:

1. DISCONNECT MACHINE FROM POWER!

2. Remove the electrical box and motor junction

box covers shown in Figure 4.

3. Use a Phillips screwdriver to remove all of

the wires that connect to the two contactors

shown in Figures 5 & 6. If any of the wires

are not clearly labeled, label them before

removing to ensure that they will be replaced

in the proper locations. Refer to SECTION 8:
